FUSE HOUSING- Specification of Letters Patent.

Patented Feb. 1.2, 1907.

Application filed July 31, 1906. Serial No. 328.561.

Be it known that I, KARL \Nrnsnn, a subject oi the Emperor of Germany, and a resident of Esscn-Ruttenscheid, Germany, have invented certain new and useful Improvements in Fuse-Housings, of which the followmg is a specification.

The present invention rel ates to those fusehousings which are provided with a rotatable timing cap held to the fuse -body by means of screws, such housing being in parti ilar used for mechanical time-fuses.

The object of the invention is to improve the connection between the tirning-cap and the fuse-body in such a manner that when the holding-screws are tightened their pres sure is distributed over a great surface, there by preventing the timing-cap packing or perniaiienlly binding against the fuse-body.

in the accompanying drawings one c1nbodiment of the invention is shown by way oi example.

Figure 1 is a longitudinal section through the fuse-housing; and Fig. 2 is a section on the line 2 2, Fig. 1.

With the timing-cap A engage the holdingscrews a, which have flattened inner ends to lie against a ring C preferably made of resilient metal, such as brass or steel. The ring (I can. turn loosely on the bottom of a groove 6 cut into the cylindrical trunnion or seat I) of the fuse-body B. The ring is split at c, Fig. 2, to permit it to be introduced in the groove D The width of the ring 0 corresponds to the width of the groove 6 so as to prevent axial movement of the ring in the groove. The ring is provided with a flange c, agaii'ist which the inner ends of the screws a. lie and which prevents axial movement of the cap A on the trunnion I).

When the screws a are tightened, the ring acts as a means to impart pressure from the screws to the fuse-body by distributing their pressure on the entire bottom oi. the groove thereby preventing ti: 0 tin 1ing-cap p aching or permanently binding against the tusebody. When the cap A is rotated, the ring 0 is carried along by the screws (1/ and slides on the bottom of the groove 6 In the embodiment shown in the drawings the timing-cap surrounds the :luse-body B; but it is evident that the arrangement might be reversed so as to have the i llSQr-lflitly surrounding the timing-cap. In such case the holding-screws a would be screwed into the fuse-body B and the ring C would lie in a groove in tl 1c timing-cap A.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a fuse-housing, the combination with the fuse-body and the rotatable timing-cap, of screws arranged in one of said parts, and means arranged between the ends OI' the screws and the other part and adapted to impart pressure from .the screws to the other part.

2. In a fuse-housing, the combination. with the fuse-body and the rotatable timing-cap, of screws arranged in one of said parts, and a ring interposed between the ends 01'' the screws and the other part.

3. In a fuse-housing, the combination with the iusebody and the rotatable rin'iingmap, one of said parts having an annular groove therein, of a resilient ring in said roove, and screws arranged. in. the other part and bear ing against said. ring.

The foregoing specification signed. at Dusseldorf this 20th day of June, I one In presence of- WILLIAM EssENWEIN, ALFR. IOHLMEYER.
